5/7=x/10

Cross multiply

(5)(10)=50

(7)(x)=7x

7x=50

Divide by 7 for both sides

7x/7=50/7

x=50/7 or x=7 1/7

Answer: x=50/7 or x=7 1/7

Answer:

x = $\frac{50}{7}$

Step-by-step explanation:

With fractions, you can cross multiply

$\frac{5}{7} =\frac{x}{10}\\10*5 = 7*x\\50 = 7x\\x = \frac{50}{7}$

Double check:

$\frac{5}{7} =\frac{\frac{50}{7}}{10}\\\frac{5}{7}=\frac{50}{700}=\frac{5}{7}$

Your friend has $90 when he goes to the fair. He spends $5 to enter the fair and $15 on food. Rides at the fair cost $1.50 per r

Maksim231197 [3]

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that ,

Total money he takes while going to the fair = $90

Money he spends to enter the fair = $5

Money he spends on food =$15

Total he spent now is given by

$\$5+\$15=\$20$

Now, he spend on rides at the fair i.e. 1.50 per ride .

Let the number of rides be x

So, cost incurred on rides = 1.5x

So, the spending money can be expressed as

$20+1.50x$

Now, remaining money left to him after spending on x rides too is

$90-(1.50x+20)\\\\=90-1.50x-20\\\\=70-1.5x$

Let f(x) denotes the function used to determine the money he has left over after rides .

So it becomes

$f(x)=70-1.50x\\\\f(x)=-1.50x+70$

Use the quadratic formula to solve for the roots of the following equation.<br> x 2 – 4x + 13 = 0

Artyom0805 [142]

Quadratic Formula: $x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$ , with a = x^2 coefficient, b = x coefficient, and c = constant

With our equation, plug in the values:

$x=\frac{4\pm \sqrt{(-4)^2-4*1*13}}{2*1}$

Next, solve the exponent and multiplications:

$x=\frac{4\pm \sqrt{16-52}}{2}$

Next, solve the subtraction:

$x=\frac{4\pm \sqrt{-36}}{2}$

Next, factor out i (i = √-1):

$x=\frac{4\pm \sqrt{36}i}{2}$

Next, solve the square root:

$x=\frac{4\pm 6i}{2}$

Lastly, divide and <u>your answer is:</u>

$x=2\pm 3i$
